How do Shivam come to the JUNGLE?

1)Sharon COULDNOT have called him as there was NO network coverage.

2)He could have called at Sharon's landline and her servant and he wud have told Shivam that Sharon had gone to Rey's house BUT how did he know that they'll use the SHORTCUT way.

3)He wud be going somewhere else and he wud have seen that car so he wud have come to see if anyone needs help BUT Shivam just cares about himself so he wouldnot care if someone else needs help!!

So I think Shivam STALKED Sharon till the Jungle!!

Bt its my IMAGINATION!! What do you guys think about it??
